question!

Okay so my plant is about a month old, its lookin good and very healthy, a nice dark green
But the very tips of my leaves are curling down, their not browning though?

Any ideas to what's causing this?

too much nitrogen ?

^That's my guess too, a tad bit too much N. Are the leaf tips starting to burn a little? Back off the feeding a little, and they should be fine.

No their not browning whatsoever, I feed them with 20 - 20 - 20

I wonder why 70% of questions asked in this section all have to do with too much/too less nitrogen. As Jaw said, cut down on the nutes. I would flush first. You could also be over watering them. It could be a few different things. I wouldn't worry too much about it, though.

If you're mixing it full strength, they WILL be browning. Even half strength(10-10-10) is pretty strong. Go with 1/4 strength,(5-5-5) when they need fed, IF, they need fed. I stress that, because I know how tempting it is to think "More nutes = bigger plants", and how easy it is to overdo it. They're not like animals, they only use what the require, and after that, the excess is harmful. To speed things up, you need to add more light. Sorry, not preaching, just thinking out loud.LOL Overfeeding is a common mistake, I've done it myself.

That isn't how nutrient ratios work.

A 1-1-1 is a 20-20-20 when it comes to ratio. The thing about a 20-20-20 is that at least 60 percent of the fertilizer is nutrient. This means it is definitely a dry nutrient. The amount of dry nutrient used is the thing to consider, and absent an EC meter I cannot be very accurate.

I think 1tsp per gallon of this stuff is probably too much for a soil system.

But as said above, a little less food is definitely required (but that doesn't make your ratio a 5-5-5, the final ratios are going to be much lower when mixed in water). I think 1/2 a tsp to 1/4 a tsp per gallon of this fertilizer will keep your plants happy in their soil. If you do wind up with a nutritional issue then you should focus on your root zone.

Do you have enough aeration material? Sometimes root damage will manifest as a deficiency affecting the outer most parts of the plant.

^Agreed, and thank you for the correction.


1/4 strength, as suggested.lol Seriously though, with most powder ferts, you can use that generic math I provided, and get you into the 'safe range'(0-10'ish) that most cannabis specific ferts offer, lower doses, at more frequent intervals. Works well, in a pinch.

Id say probly too much N. Although a pic would help out as well. Flush her and take it easy on the nutes you should be good.
